Overcurrent shut-off during deceleration

Hva betyr OC During Dec ?

The inverter output is shut off because the output current reached or exceeded approximately 200% of the rated current during the deceleration phase. This can be caused by too rapid deceleration, issues with mechanical braking, or a fault in the motor/wiring.

• Motor decelerating too rapidly for the load or inverter's braking capability.
• Output short-circuit or ground fault occurring during deceleration.
• Mechanical brake on the motor engaging too quickly or aggressively.

1. 1

   Increase the deceleration time setting (e.g., Pr. 8 or Pr. 45) to allow for a smoother slowdown.

2. 2

   Adjust the operation of the motor's mechanical brake to ensure it is not engaging too quickly or causing excessive current spikes.

3. 3

   Inspect motor cable and motor terminals for signs of short-circuit or ground fault.
